1 that I know of.

 

Only one. He's been on it for a couple years now and is still ” working the kinks out of the tune” Jessie aka silveronyx aka trueblue Motorsports

I would go with an 80 Robert :2cents:

 

Thanks Eric and Matt. I thought he already had everything worked out and that's why he is selling the kit. Oh well.

 

I was thinking the other day how much I would like a whipple, 3.08 gear and a 6l80. Price is a big reason why its just a pipe dream for me. It is expensive!

 

That would be a nice combo!

 

Unless ur gonna go big power Robert I would just build the 70 with one of the vendors here that have lots of experience with our trucks

 

Well I'm pretty sure l92 heads, cam and a 100 shot will put me at some pretty big power

 

You could run a built 70 all day with that power.

 

I'd go phoenix 80 then

 

Hmmmm not quit sure which way I will go.

 

There are no other Trailblazers with a 6L80/90 besides mine. Colorados and Canyons, yeah, but no TB's. Unless you're planning for more power or you've gotten fed up with rebuilding 4L70's I can't provide anyone with a reasonable reason for spending the bucks, besides "I just want one."

Yes the trans swap kills several birds with one stone (stronger, greater gear multiplication, potential greater fuel efficiency). But for what most people expect out of and use their TBSS for, it's an expensive proposition...especially if you're an '06 E40 AWD!

Not too many are interested until I can turn in a magic quarter mile time. Over the holidays I was able to get a 13.75@100 w/a 2.04 60ft. Not bad for a full weight 5200+lb AWD pig with heavy, 20x10 wheels, all season tires, pump gas, and CAI and cat-back. But I still know there was more in there because it rolled out the line (wanted more timing and fuel) and had 2 slight shift delays (it spins the motor so quickly and into parameters well beyond what the factory tune allows... whips past redline so fast in first gear!). I could have cheated and dropped the spare, taken out the rear seats, gone with lighter wheels, etc. But I'm not into sensationalism.

As stated in another thread, the reason I have yet to demonstrate its full potential is twofold. A) The amount of insane power limitations that are programmed into '07-09 TBSS's E67's is mind boggling. I'm always finding new areas of calibrations that GM snuck in to suppress the power of the LS2 in our applications. Sure I could cheat and play with PE and Spark like most tuners, but I'm trying to develop a full base dynamic engine calibration to consistently run wicked fast, still sit in traffic w/o overheating, still tow, and deal with 4 season temps. No to mention we want a transmission calibration that shifts hard when at WOT, but is smooth like butter otherwise, right? B) Time. Too many irons in the fire. Other 6L80/90 vehicle project inquiries, wrapping up college degrees, exhaust and valances, plus other miscellaneous projects.

I'd like to get the price down for more to get in, but as I can't at this point, I'm just enjoying having 2 of 2 6L80 TB's.

 

Putting one in now







I am putting one in my 03 Sonoma behind a 6.0 L L76 with a TBSS ECM & tune. I think we will be able to start it up in a couple days and concerned that I picked the right tune. I was told that the CTS-V tune was the right one for my engine, but the ECM tuner used a TBSS. How did you get the ECM to talke to the Transmission Controller?
Am I on the right track?

 

I'd settle for the 3.42's. Do they make 3.08's for our axle?
Don't forget to add a mild converter in there, maybe 2600-2800?

Jesse, correct me if I am wrong, but one TB with 6L80e, and one with 6L90e?

I think Jesse nailed it...it's more a really nice option, but very hard to justify the economics, at least at this time.

I'd absolutely love one, but, again, a bit tough on the wallet.
Seeing how I want a maggie as well, I am thinking of getting a used CTS-V, as it comes with both, with, perhaps, some powertrain warranty still in effect.

 

3,42 damn!! im goin 3.73

 

They are talking 6 spd autos here. The first three gears are steep.

 

I seriously considered it...that and a T56....but I thought cost was a big obstacle, not to mention time and my own limitations of the actual skills to do it...Instead, my 4L80 and converter are $6gs...proven and working....some skill required to install, but no GM engineering required... Im guessing it would have cost $10-$12k to do a correct T56 install and w/o a guarantee of it working, I ditched that idea....but that was hard to do - there is something really sexy about being the first to do it - Jesse knows how that feels.... The 6L80 would be sweet as well...but I think Jesse mentioned a $9kish install.... Personally if I was going to shell out $9g's I would have just thrown my balls on the table and tried the T56...just didn't have the sack to do it this year....maybe someday, but probably not...

TCI has some 6-speeds out that are in a 4L80 case...look interesting - would be cool to see if that can be incorporated into our trucks w/ either TCM mod, or using TCI's control...

 

4l80e can be done very reasonable and I wouldnt take a 2nd look at 4L70E. Far more failures than their should be built or not! Sure theres a few exceptions but they are rare! my 80E drove MUCH better!

 

I beat the crap out of my lvl 7 from FLT.

 

I say stay with the 4l70 as long as you can. There are some fast cars out there on 60-70's. The advantage with the 6L is the extra gearing which isn't always best for drag racing but does feel nice and also gets better fuel mileage.

The 80 is a awesome option but I would save that for 600 rwhp +

 

Ya I am pretty sure I am going to stay with the 70. I have over 40k on my stock trans and it still feels really good. I think it all boils down to how you treat it and maintain it.

 

As a bonus wouldn't you be getting better milage with the 6l80? Also am I have to be missing something with the price cause the tbmsport ecu is $1525 and a tranny is like $900 - $1500 used. What else has to be done? Where is the cost coming from?

 

I was wondering the same thing but just thought people knew something I didn't. I think the only thing your missing is pricing for a driveline and a gasket kit.

 

Hey fellas thinking about doing a swap to a six speed auto. What's the best tranny to go with and what mods do i need to do to complete the job 100%

 

6L90e is probably the best to get.

Talk with Jesse.

 

lol. good luck

 

It's more like 4500$ with you doing the work. A lot depends on awd vs. 2wd and 6l80e or 6l90e. Used Trans is 900-1500$. The ecu and stuff from Jessie is more like 2200$ then depending on transmission you need to have your drive shaft shortened 300-500$ then a tune, and gears if you are changing those as well. Also dipstick, fluid, filter, gaskets, and any other miscellaneous things that come about.

 

What does AWD add to the mix? Sorry if that's a dumb question.

 

The lengths of the 4L70/6L80/6L90 are each different PLUS they have different output shafts. So based upon which transmission you choose to put in your truck, the added costs include a new adapter, input gears and adjustments to the driveshafts' lengths.

Man, when I looked this up the other day, the prices weren't that bad for the kit. If I can do this for a grand for the electronic side of the house.. I'd do it I can get the Trans cheap / easily.

If you have a RWD TBSS and a good local tuner, then the electronics side can easily be done for under $1k.

Did all the "bugs" get worked out of the 6l80e swap yet?

Major bugs have been worked out. It was all a matter of tuning and having people who have EXTENSIVE knowledge in tuning...i.e. not just spark and power enrichment "tuners".

I've ridden in a 6L80E TBSS that was using T43. It does work. I expect most transmission bugs would be tuning issues. I know you need EFI Live at least for the segment swap. I think HP Tuners will work after that.

EFILive is the preferred software to seemlessly complete the conversion. Any other software and you're itching for unnecessary frustration.

So assuming you find a good tuner to go in and play with the GM tables, this seems doable...

You have to fundamentally understand the correct language and acronym of components. PCM=powertrain control module. These ran the engine AND transmission. ECM- Engine control module. TCM=Transmission control module. The work was segregated to individual modules to aid in programming and vehicle at the OEM level. So if it's an "ECM", it's decided to be compatible with a certain type/set of TCMs.

As your truck came with a PCM from the factory, basically anything you use will work, but you have to make sure that you choose the right ECM, operating system within the ECM, TCM, OS inside the TCM, and proper pin connections in your harness to be compatible with your gauges and other stuff.

The new world of automotive control modules should not be thought about as simple modular mix and match like it was in the 90's. You have to think more like your laptop or mobile device. Apps have to play nice-nice with each other. Windows 8 stuff may not work with Windows XP. Windows stuff may not work with Apple stuff, etc. So before just grabbing any LS engine and any ol' LS engine harness and thinking it'll automatically know what it's doing bc you pair it with any ol' GM transmission you should consult with people who have actually performed and/or researched GM's extensive electronics compatibility system...or you'll be throwing money at this project and end up parting it out to regain your sanity.

is it true that RPM from santa clarita built one ?they said they got it working after a bunch of bs tuning and they would never do it again..

RPM did my first TBSS 6L90 customer's conversion. It was a royal PITA due primarily to the a miswired harness (my fault) that fried the TCM, and wrong TCMs being ordered/delivered to the local dealer (shared fault). It took a few months to pinpoint the various small problems (including me having to fly out there to put my hands on the truck itself) but in the end we got it all worked out and, of course, learned some new details to the GM electronic heirarchy labyrinth. I took a most unrefreshing bath on that order, but most importantly, the customer got his truck back and running as he liked. I caught up with him a few months ago and we tweaked his trans tune for him because he wanted better downshifts.

 

It adds more $$$$$$ out of pocket!:muahaha:

 

Thanks. I'm reading all about it now...
